- org.springframework.boot.context.annotation.Configurations

Direct Known Subclasses:
UserConfigurations
```
public abstract class Configurations
extends Object
```
A set of @Configuration classes that can be registered in ApplicationContext. Classes can be returned from one or more Configurations instances by using getClasses(Configurations[]). The resulting array follows the ordering rules usually applied by the ApplicationContext and/or custom ImportSelector implementations.
This class is primarily intended for use with tests that need to specify configuration classes but can't use SpringRunner.
Implementations of this class should be annotated with @Order or implement Ordered.
Since:
2.0.0
